ok, so, let me give you all the details, i live in socal and have an 04 mt rx8 with 67000 miles on it, so im out of warranty, obviously, about a month ago i installed the greddy turbo kit, i know, not the brightest idea, also have the agency exhaust with the midpipe installed, agency power pulley, and the profec b II boost controller, did fix #2, i use 5w30 castrol sythetic oil, do not have a bov installed yet, but have one ready for when i do get my car working again, did not get a chance to have the emanage ultimate tuned

alright, so when i first started the car after i installed the turbo, car seemed to stall a lot, and was also running very rich, as expected, peak boost was at about 7psi, spiked to 9 occasionally, i think i used the right terminology for that, but overall the car ran fine and sounded great, so one night i decided to take a friend out for a drive, and after a couple hard pulls, i noticed that the car had lost some power, pulled into a neighborhood to check and see what the problem was, didn't notice a big difference in idle, except that the car shook a little once the rpm's dipped below 750, afterwards, when i tried to floor it, the car hesitated a bit and felt like it had lost some power, but it stilled boosted to 7 psi and the hesitations seemed to be random, sometimes the car accelerated fine, other times it would hesitate more than others

decided i had to have someone take a look at it, so i took the car to mazdatrix in long beach, i asked them if they could check my ignition coils, so they did, and they checked out fine, had one of the mechanics come out and listen to the car idle, he told me he didn't want to be the bearer of bad news, but i might have blown an apex seal, of course my heart dropped and i asked him how much it would cost to fix something like that, he told me the numbers and of course you all know how steep the prices are for rebuilds, he told me to come back the next day to have a compression test done and also check the spark plugs as well

unfortunately, i never got a chance to make it back to them for the compression test, i had to drive to school the next day, and while taking the 22 west exit on ramp, my car suddenly died on me and i could not restart the car, called mazda roadside assistance and had them tow the car to my house so i could figure out myself what the problem was, so i changed the spark plugs and wires, had the battery and alternator tested, turned out the alternator was bad, so i got a remanufactured one, also repalced the battery with a red top, tried to do a compression test myself with a gauge kit from autozone, not sure i did the test correctly, but it seemed like the engine had enough compression, anyhow, i put everything back in and tried to start the car, but it just turned over, and did not start, gave it a little gas, and eventually it started, however, i had to keep my foot on the gas to keep the car from dying, as soon as the rpm's come anywhere near 1000, the car shakes like no other, and sounds like a 20b on steroids, can rev the car fine, but anywhere near that 1000 rpm mark the car just shakes and wont hold idle, now, i have done everything in my power to fix what might have been wrong with the car, but i have no where else to turn, and the only answers i get from mazdatrix are you got a blown seal, which may be true, but the car should be able to stay on even with a broken seal, so if anyone could please help me out on this, i would appreciate it so much, maybe someone living in socal that could come out to take a look at my car to help me figure this out, i am available all weekend

 

Seriously speaking, it does sound like a blown(or crack, whatever) apex seal issue.

you didnt tune your car ? Thats the stupidest move. and NO BOV? what the hell were you thinking ? and you were *pulling hard* without doing everything I said before? wow you deserves a blown apex seal.

When an Apex seal blown, the idle will not hold, most of the time it just dies off, why? poor sealing, little to no compression.

Have it check at Mazdatrix. the Apex seal itself is cheap, but the labor will kill you. Not to mention the blown/broken seal might come off and take some other parts of the engine with it. Worst case scenario is you might have to replace the housing and might be the rotor itself. or even worst, totally trashed and need to buy a new motor.

It does not matter if you're out of warranty or not, whenever you install a Turbo, your motor warranty is gone. Sure you can put everything back to stock, but labor aint cheap. not to mention techs are stupid, but not blind, they can tell if it has been *tempered* before.

 

thanks nycgps, i know it wasn't the smartest decision to run the car hard without tuning, so please dont give me a hard time, it was just too much fun putting my foot on the gas at the time, and i guess this will definitely cost me, any idea where i could get another engine though, because rebuilding it is just gonna be too expensive, and again thanks for your quick response, i really appreciate it

 

Mazmart might be the place that you need.

One of our forum vendor they have one of the most famous guy to do engine rebuild. You might want to leave a message there or just PM paul directly.

 

just sent mazmart a message, hopefully he can help me out on this, thanks for refering me to them nycgps, hopefully i will get out of this mess with not too big of a hole in my wallet

 

Pop goes the Rene.

Zoom Zoom Boom.

You can pick up a good motor at a junk yard for $2k - $3k, depending on where you live.

 

it is 2-3K from local junk yard. I've seen one at one of the local junk yard for 1.5K, reason why its so cheap because "no one seems to want it". Well, thats what the guy told me. I didnt get it because Im not sure what kind of damage it has, he said it came from a car that got hit from the rear and total. maybe next time. I bet the motor is still there

but for 2-3 K, you can get a nice rebuild from one of the most famous Rotary rebuilder @ Mazmart. (plus your core, of course)

 

ok, well, def looks like i need to go engine hunting, and again thanks for the help guys

 

New engine, well I would fore shore be gett'n it ported.
I would contact Charles Ray Hill on that. You can check out his Rene rebuild here

https://www.rx8club.com/series-i-major-horsepower-upgrades-93/rebuilding-my-renesis-115104/

 

Rebuilding a Renesis for $2k would be quite a trick, unless you really cut corners.
Just the seals and gaskets are $1600.
Since this motor is blown, you are looking at replacing at LEAST one housing at $500 and potentially one or two side housings at $300 and one rotor (if it got gouged) at $500.
And this presumes you are doing it yourself.

 

well, im definitely in a pickle, but there ain't no way in hell i could rebuild the thing myself, i had a hard enough time putting in the turbo kit, and not doing that correctly is what got me into this situation in the first place, looks like I found a used long block with 41000 miles on it at a junkyard in Alabama, talked to the guy there and he told me the car was rear ended and totalled, so the engine compartment was untouched, he told me he could ship it to my door for $1600, and then I would just need to have Mazdatrix drop it in for me, hopefully the labor wont be too much on that, anybody think this engine is too good of a deal? didn't see the engine myself, i just received an email from the guy after searching the web, im on a college salary, lol, so this is looking like the cheapest avenue, just dont wanna make a mistake in buying a motor that could be damaged too, argh, idk what to do, somebody help me ease my stress, im barely twenty and this car is already giving me gray hair lol

 

sorry to hear... hopefully someone somewhere will read this and learn from your mistakes, so its not a total waste.

don't push the car for what its not prepared to do.

 

That price for the junkyard motor is really good.
I'd go for it.
Once you get it, strap the tranny and starter motor onto it and get a compression check.

 

yup i know that now, i deserve a spanking just like your monkey lol, no zoom without a tune

 

yeah, def seems like the best option, and im for sure gonna do a compression check on it before i put it in, as we all know no one engine is the same, and even with 41000 it might already be dead, but im gonna hope for the best here, thanks mm, i just put in the order so i should have it by the end of the week, ill have the car towed to mazdatrix and maybe they can get started on taking the engine out and by the time the motor gets here i can have everything ready for the new/old/second one, as well as the compression test, ill save my old one, and maybe rebuild it myself incase i have any problems in the future, this may turn out to be advantageous after all

 

Sounds like a good plan.
Good luck!

 

HAVE U CHECKED THE AIRFLOW METER IT WONT RUN WITHOUT IT and if you have a hose off between it and the engine it wont run right the computer uses the data of how much air is coming in to determine how much fuel to add and with boost you may blown off a hose or the two nipples at the end of the intake were they meet the rotor housing check the obvious before you start looking for a block also call pfsupercars in maryland or atkins rotory on a rebuild if your gonna take it out ya might as well port it and put the big apex seals in it

 

What ECU system are you using?

 

Why? Our Engine ported wont do much. Just add some more HP in the top end thats about it. But not get up and fly kind of HP.
